While drivers may remember to "reach across your body" with opposite arm because they're in driving-mode, passengers probably won't-- from personal observation.

Specifically, this is from experience involving a passenger door opening into a curb-side bicycle lane. The door opened before the car came to a complete stop and quite a ways back from the intersection. The car was still compressing front springs from braking when passenger door opened. (Enough other posts here today described what happened next.)

Since then, I wear bold red striped shirts or jackets when riding and red helmet.

When they found "Where's Waldo" (or "Where's Wally" for those from UK), I know that they've seen me, and that's the whole point.

I've used this very successfully in my present home of Vancouver, BC. Previously, it also worked well when residing in SF and Seattle. There was a confirmed Waldo sighting near English Bay just yesterday, but now you can call me by my real name.
